Harrod Concrete and Stone Company

centennial

David Harrod owns a 500 acre underground stone quarry in Frankfort, Kentucky. The facility, now Harrod Concrete and Stone has played a significant role in the highway construction industry in central Kentucky since the early 1970’s. In addition to the quarry, the Company is a major supplier of concrete to the region and supports its operations with a large fleet of trucks. The quarry was experiencing poor power quality in its underground mine and as a result was being assessed a power factor penalty and a kilo watt demand penalty by the local utility company. Management was concerned that the poor power quality would have an effect on the life of the equipment critical to the quarry’s daily operation. EESI Global was brought in to assess the situation and to make recommendations on lowering the facilities electric utility cost and eliminating the power factor and kilo watt demand penalties the facility was experiencing. Management’s goal was to see if this could be accomplished within a 36 month payback period. EESI Global far exceeded expectations by delivering a 20% savings within an 18 month payback period.
